Final answer:
According to traffic laws, it is illegal to follow a fire vehicle or ambulance responding to a call within 150 m to ensure the safety of emergency responders and allow them to reach their destination quickly and efficiently.
Step-by-step explanation:
According to traffic laws, if a fire vehicle or ambulance responding to a call is in any lane going in the same direction as you ahead, it is illegal to follow them within 150 m. The reason behind this rule is to ensure the safety of emergency responders and give them enough space to navigate the road without obstruction. Following them too closely can hinder their progress and potentially cause accidents. By maintaining a safe distance of at least 150 m, you allow emergency vehicles to reach their destination quickly and efficiently, ensuring timely assistance to those in need.
